WebPheromones may act to control caste differentiation through hormonal action, but it is not clear how this mechanism works. Activation of the corpora allata near the brain may result in release of a hormone, distinct from the juvenile hormone, that causes differentiation of a nymph into a soldier. WebJan 1, 1979 · Insect growth regulators (juvenoids and chitin deposition inhibitors) have also been tested in field trials to control termites (e.g. Howard and Haverty, 1979; Doki et al., …

Juvenile Hormone Epoxide Hydrolase: a Promising Target for
WebTwo simple chromenes with anti-JH activity have been isolated and identified from the bedding plant Ageratum houstonianum. By contact and fumigation these compounds induce precocious metamorphosis and sterilization in several hemipteran species of insects. Certain holometabolous species are sterilized, forced into diapause, or both. WebTermite colonies are typically founded by a pair of sexually reproducing dispersers, which can sometimes be replaced by some of their offspring. ... Juvenile hormone titer regulates soldier differentiation in termites (Liu et al. 2005; Mao et al. 2005; Cornette et al. 2008) and therefore represents a good proximate candidate for the selection ... WebNov 21, 2024 · Juvenile hormones (JHs) are a group of structurally related sesquiterpenes secreted by the insect corpora allata. They affect most insect life-cycle stages and physiological functions, including embryogenesis, larval and adult development, metamorphosis, reproduction, metabolism, diapause, polyethism, and migration. shot holding cell phone
